Answer:
Carbon dioxide can be collected over water. Carbon dioxide is slightly soluble in water and denser than air, so another way to collect it is in a dry, upright gas jar.
Explanation:
Answer:
New temperature = 546 K
Explanation:
Given that,
Initial volume, V = 200 L
Initial temperature, T = 273 K
We need to find the new temperature if the volume is doubled.
The relation between temperature and volume is direction. If volume is doubled, it means the temperature gets also doubled.
New temperature of the gas = 2(273) = 546 K
Answer:
Explanation:
The fundamental units of a measurement is known as its base unit. The units of these substances serves as the base through which other quantities depends. Examples of such quantities are mass, length, time, electric current, temperature, amount of substance and luminous intensity.
Derived units are those that results from the combination of the fundamental or basic units. Examples of derived quantities are force, volume, density, pressure e.t.c.
Derived units of Density:
kgm⁻³
gcm⁻³
Derived unit of volume:
m³
cm³
mL
L
dm³
Answer:
correct answer is precipitation and evaporation
Explanation:
solution
correct answer is precipitation and evaporation because in the evaporation process of water cycle, the atmosphere is directly interact with the hydrosphere as water changes from liquid into vapor or gas form
and Precipitation is the process when water that may be in the form of snow or hail or rain etc that is fall from the cloud into the open sky
so correct answer is precipitation and evaporation
The answer is D because large hydrocarbons have a higher number of carbon which means an increase in boiling point and also rate of flow decreases, so they become solids.
